DETAILED DESCRIPTION OF THE DRAWINGS Referring now to the drawings and more specifically to FIG. 1, it will be seen that one embodiment of the novel mounting structure designated generally by the reference numeral is there shown. This mounting structure 10 is illustrated in mounting relation with respect to turbine ventilator 11 which revolves in response to the action of wind upon the turbine blades. The adjustable mounting structure 10 includes a substantially flat, generally rectangular shaped base plate 12 which is preferably constructed of a suitable rigid metallic material such as sheet steel or the like. The base plate has a centrally located circular opening 13 therein. An upturned annular flange .14 is integrally formed with the base plate and circumscribed said circular opening 13. It will be noted that the annular flange 14 has an annular lip 15 integrally formed therewith and projecting radially inwardly therefrom.

The base plate 12 is adapted to be mounted upon the upper surface or roof of a building structure so that the opening 13 is disposed in registery or communicating relation with an opening 0 formed in the roof. The turbine ventilator serves to exhaust hot humid air from the attic space below the roof through the opening 0. The base 12 may be secured to the roof structure by any suitable means, such as nails or the like in a well-known manner.

The mounting structure also includes a lower cylindrical section which is also constructed of a suitable rigid metallic material, such as sheet steel or the like. This lower cylindrical section 16 has a lower edge 17 which as shown is disposed in a plane which is substantially normal to the longitudinal axis of the lower section. The lower end portion of the lower section is telescopically positioned around the upturned annular flange 14 as best seen in FIGS. 1 and 2.

Means are provided for releasably locking the lower section 16 to the base plate and this means includes a plurality of similar locking members or clips 18. Each of these locking members 18, as best seen in FIG. 5, is formed of an elongate, substantially flat, strip of metal which is normally generally vertically oriented during use and has the upper end thereof bent at substantial right angles to the major portion thereof as at 19, and which terminates in a reduced end that defines an anchoring element 20. Each locking member 18 has a threaded aperture 21 therein and the lower portion of the locking member is bent first inwardly and then outwardly to form a channel shaped locking portion 22.

The lower cylindrical section 16 has a plurality of openings 23 therein through which project bolts 24, each of which engages a threaded aperture 21 of one of the locking members 18. The anchoring element 20 of each locking member projects through an opening 25 in the lower cylindrical section 16 and this opening 25 is of generally rectangular configuration. With this arrangement, the channel shaped locking portion 22 of each locking member is adapted to engage and be clamped against the lip 15 when the bolt 24 is revolved to pull the locking member in an outward direction. These locking members are disposed interiorly of the lower section and serve to very eflectively but releasably innerlock the lower section to the base plate 12.

The upper marginal portion of the lower cylindrical section 16 has an outwardly projecting annular bead 26 formed thereat to impart rigidity to this upper edge portion. The upper edge of the lower cylindrical section is bent outwardly from the bead 26, as at 27, so that an outwardly facing annular groove 28 is defined. It will be noted that the bead 26, outwardly projecting upper edge 27, and annular groove 28 are all obliquely disposed with respect to the longitudinal axis of the lower section.

The mounting structure 10 also includes a generally cylindrical upper section 29 which is also formed from a suitable rigid metallic material, such as sheet steel or the like, and which has an upper end edge disposed in a plane substantially normal to the longitudinal axis of the upper section. The upper cylindrical section 29 is adapted to support the turbine ventilator 11 thereon in a wellknown manner. The steel throat band 30 of the turbine ventilator is fixedly but releasably secured to the upper cylindrical section 29 so that the axis of rotation of the turbine is disposed substantially vertically. Since the adjustable mounting structure It is often applied to a slanting roof structure, it is necessary to adjust the lower section and upper section relative to each other to dispose the axis of rotation of the turbine so that it is substantially normal to the horizontal.

Therefore, the lower edge portion of the upper cylindrical section has an outwardly pressed annular head 31 formed thereat to impart rigidity thereto and the lower peripheral edge 32 of the upper cylindrical section projects radially inwardly from the bead. This lower end edge 32 projects into the annular groove 28 and engages the upper exterior surface of the bead 26 on the lower cylindrical section. Similarly, the radially outwardly projecting edge 27 of the lower section projects into the annular groove defined by the head 31.

With this arrangement the upper and lower cylindrical sections are interconnected together by the inter-engaging parts so that these sections may be rotated relative to each other. These inter-engaging annular elements of the upper and lower sections are disposed generally in a plane disposed obliquely or angularly with respect to the longitudinal axis of the sections. It will, therefore be seen that by rotating the sections relative to each other, a wide range of adjustment may be accomplished for the purpose of disposing the axis of rotation of the turbine so that it is positioned substantially normal to the horizontal.

The upper cylindrical section 29 is is also provided with a plurality of similar locking members or clips 18 identical in construction to those used in conjunction with the lower section. In this regard, the upper section 29 has a plurality of openings 33 therein through which the bolts 24 project and threadedly engage the locking members. The anchoring element 20 of each locking element also projects through a generally rectangular shaped opening 34 formed in the upper section. It will be noted that the channel shaped locking portion 22 of each locking member engages the inwardly projecting marginal portion of the lower section which is defined by the annual groove 28. Thus the inwardly projecting annual convexity as defined by the annular groove 28 is very snugly but releasably engaged by the channel shaped locking portion of each locking member thus releasably locking the upper and lower sections against relative rotation therebetween.

The mounting structure 10, constituting the present invention, allows the turbine ventilator supported thereby to be eflectively and properly mounted on a roof or similar structure even though the roof may be a slanted or pitched type roof. Since the lower edge portion of the lower section is telescopically disposed over the upturned flange 14, a very effective watertight connection is provided thereat so that water cannot flow interiorly through the opening 13. Further, the use of the unique locking members permits efiective but releasable interlocking of the upper and lower sections together and to the base plate 12.

Thus it will be seen that I have provided a novel adjustable mounting structure, for turbine type ventilators, which is not only of simple and inexpensive construction but one which functions in a more efficient manner than heretofore known comparable devices.

It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the various parts without departing from the scope of my invention.
